Product Description


BENTLY 3500/61 163179-02 6-Channel Temperature Monitor with Recorder Outputs
RTD/TC Input, Programmable Alarms & Recorder Outputs for Rotating Machinery Condition Monitoring
1. Product Overview

The BENTLY 3500/61 163179-02 is a six-channel temperature monitoring module from the Bently Nevada 3500 machinery protection system, designed for real-time temperature monitoring of critical rotating machinery components (bearings, windings, gearboxes, etc.). It accepts both RTD (Resistance Temperature Detector) and Thermocouple (TC) inputs, processes signals with high precision, and compares them against user-programmable alarm setpoints to trigger alerts or shutdowns when thresholds are exceeded. A key distinction from the 3500/60 is its dedicated recorder output per channel, enabling seamless integration with data acquisition systems for trend analysis and post-incident diagnostics. The module supports RTD/TC non-isolated or TC isolated I/O configurations, with flexible internal/external termination options, and integrates with the 3500 rack and configuration software for centralized monitoring and control. Certified for harsh industrial environments, it is widely used in power generation, oil & gas, petrochemical, and heavy manufacturing to enhance machinery reliability and prevent catastrophic failures.
